To make this little clip I took 150000 shots. Why so many? Because macro photography involves shallow depth of field. To extend it, I used focus stacking. Each frame of the video is actually a stack that consists of 3-12 shots where in-focus areas are merged. Just the intro and last scene are regular real-time footage. One frame required about 10 minutes of processing time (raw conversion + stacking). Unfortunately, the success rate was very low due to copious technical challenges and I spent almost 9 long months just to learn how to make these kinds of videos and understand how to work with these delicate creatures.
Make sure that you watch this full-screen, HD actual size. The detail is incredible.
Inspired by the water and brush calligraphy of older artists in his local Beijing parks, Hanna converted a Beijing tricycle, called a san lun che, to digitally “paint” (or more accurately drip) Chinese characters onto the sidewalk. The characters write out Dongcheng District Propaganda phrases that are on banners and housing developments in the district.
The trike would catch quite a bit of attention in the streets, as seen in these two 2011 videos by Jonah Kessel. According to Kessel, the tricycle drips:
营造 未成年人健康成长的良好环境 Create a good environment for minors to grow up healthy
文明从脚下起步 奉献从身边做起 Civilization comes from every individual, to contribute from every little thing
树文明新风 做文明市民 Be a civilized citizen and build a civilized new atmosphere for constructing s cultured and civilized city
共建文明城区 共享美好家园 Build a civilized city for everyone to share a beautiful home altogether
做文明有礼北京人 建和谐魅力新东城 Be civilized and polite Beijingers, to build a harmonious charm new Dong Cheng district together
美德贵在坚持 文明重在行动 Virtue shows through long term persistence, civilization reflects by actions
和谐东城 你我共建 Harmonious Dong Cheng District constructed by you and me
建全国文明城区 做东城文明市民 Constructs the national civilized district, to be the civilized citizen of Dong Cheng District
The project was first shown at Beijing Design Week in 2011. Hanna now lives in Los Angeles where he works as an artist and designer.
We just tried this super easy Reversing Arrow Illusion, and it is, in fact, super easy. Draw two left-pointing arrows on a piece of paper and then put a clear, empty glass between you and those arrows. When you pour water into the glass, you’ll see something that you might not expect. How exactly did that happen? From Physics Central:
No, you aren’t going crazy and you haven’t found yourself with Alice in Wonderland staring at arrows pointing in opposite directions. In fact, you have just demonstrated a physics concept called refraction, the bending of light.
When the arrow is moved to a particular distance behind the glass, it looks like it reversed itself. When light passes from one material to another, it can bend or refract. In the experiment that you just completed, light traveled from the air, through the glass, through the water, through the back of the glass, and then back through the air, before hitting the arrow. Anytime that light passes from one medium, or material, into another, it refracts.
Just because light bends when it travels through different materials, doesn’t explain why the arrow reverses itself. To explain this, you must think about the glass of water as if it is a magnifying glass. When light goes through a magnifying glass the light bends toward the center. Where the light all comes together is called the focal point, but beyond the focal point the image appears to reverse because the light rays that were bent pass each other and the light that was on the right side is now on the left and the left on the right, which makes the arrow appear to be reversed.
